I wish I could answer the EP175 question for you, but I ordered one with a custom finish a week ago and it can take up to 5 weeks for delivery. I have the On-wall M22's and an on-wall/in-wall VP100. My room size is 1800 sq ft. I've heard that if your room is 2000 sq ft or less, then the EP175 should do nicely.

I just want something to complement the on-wall M22 and be small, because it will be positioned under the VP100. I'm not looking for maximum effect for movies at this time.
